IRONPORT ASYNCOS 6.3 FOR WEB USER GUIDE
3. If the Web Proxy is deployed in transparent mode, edit the settings in Table 16-9.
Table 16-9 Transparent Proxy Mode Authentication Settings
Setting Description
Credential Encryption This setting specifies whether or not the client sends the
login credentials to the Web Proxy through an encrypted
HTTPS connection.
This setting applies to both Basic and NTLMSSP
authentication schemes, but it is particularly useful for Basic
authentication scheme because user credentials are sent as
plain text.
For more information, see “Sending Authentication
Credentials Securely” on page 363.
When you enable credential encryption using this setting,
you must also specify a TCP port in the HTTPS Redirect Port
field. This specifies through which port the client will open a
connection to the Web Proxy using HTTPS.
